[OpenBIOS] [PATCH] tcx.fs: fix size of STIP register in 8-bit mode

The existing reg property sets the size of the STIP register to 1 byte in
8-bit mode which is likely wrong, and causes NetBSD 6 to fail to detect the
the TCX card in 8-bit mode.

Use the same STIP register size as for 24-bit mode in both 8-bit and 24-bit
modes which is enough to allow NetBSD (including X) to function correctly.
